Compiler Systems and Methods for Quantum Computer with Reduced Idle Volume

3. The method of claim 2 wherein the Bell measurement is scheduled between the first memory qubit module and the first workspace qubit module.

4. The method of claim 2 wherein the Bell measurement is scheduled between the first memory qubit module and a third workspace qubit module from the first group of the workspace qubit modules.

5. The method of claim 2 wherein scheduling the one or more layers of quickswap operations includes scheduling one or more quickswap operations that move the first logical qubit of the Bell pair from the first memory qubit module to a second memory qubit module.

8. The method of claim 7 wherein the measurement operations include reactive measurement operations and wherein, after being used in a subroutine, each ancillary state is maintained in the memory qubit modules for at least a reaction time sufficient to allow decoding of output data from previously executed logical blocks.

12. The method of claim 10 wherein the quantum subroutine is specified as a unitary transformation operation and defining the quantum subroutine as a ZX diagram includes translating the unitary transformation operation to a ZX diagram.

13. The method of claim 10 wherein the quantum subroutine is specified as a reversible circuit and defining the quantum subroutine as a ZX diagram includes translating the reversible circuit into a ZX diagram.

19. The classical computer system of claim 18 wherein the measurement operations include reactive measurement operations and wherein the processor is further configured to schedule the reactive measurement operations such that, after being used in a subroutine, each ancillary state is maintained in the memory qubit modules for at least a reaction time sufficient to allow decoding of output data from previously executed logical blocks.
